Hi John,

If you're buying an Irish car then you'll be very limited in terms of choice. The vast majority of 2010 Ford Focus on the roads in Ireland are powered by the 1.6-litre TDCi diesel engine, in either 90- or 110hp states of tune). It's not a bad engine with a great performance-to-economy ratio and low road tax. Be aware though, like many engines of this type, it's only really suited to average annual mileage of 20,000km and above - or the majority of its time on a fast-flowing road/motorway. The reason is that its diesel particulate filter (DPF) can clog up and it can be expensive to remedy. There are other components in the engine itself that also gum up if the car is used predominantly for low-speed driving.

Other engines in the 2010 Focus are the 1.8 TDCi diesel and, for low-mileage drivers, the 1.4- and 1.6-litre petrol units. All of these are much rarer. The 1.8 isn't quite as susceptible as the 1.6 diesel to issues, but it's less economical. If you're sure that diesel suits your needs then seek out a 1.6.

Hope that helps
